Features

Adversarial Attacks: AdvSecureNet supports a diverse range of evasion attacks on computer vision tasks, including gradient-based, decision-based, single-step, iterative, white-box, black-box, targeted, and untargeted attacks, enabling comprehensive testing and evaluation of neural network robustness against various types of adversarial examples.

Adversarial Defenses: The toolkit includes adversarial training and ensemble adversarial training. Adversarial training incorporates adversarial examples into the training process to improve model robustness, while ensemble adversarial training uses multiple models or attacks for a more resilient defense strategy.

Evaluation Metrics: AdvSecureNet supports metrics like accuracy, robustness, transferability, and similarity. Accuracy measures performance on clean data, robustness assesses resistance to attacks, transferability evaluates how well adversarial examples deceive different models, and similarity quantifies perceptual differences using PSNR and SSIM.

Multi-GPU Support: AdvSecureNet is optimized for multi-GPU setups, enhancing the efficiency of training, evaluation, and adversarial attack generation, especially for large models and datasets or complex methods. By utilizing multiple GPUs in parallel, AdvSecureNet aims to reduce computational time, making it ideal for large-scale experiments and deep learning models.

CLI and API Interfaces: AdvSecureNet offers both CLI and API interfaces. The CLI allows for quick execution of attacks, defenses, and evaluations, while the API provides advanced integration and extension within user applications.

External Configuration Files: The toolkit supports YAML configuration files for easy parameter tuning and experimentation. This feature enables users to share experiments, reproduce results, and manage setups effectively, facilitating collaboration and comparison.

Built-in Models and Datasets Support: AdvSecureNet supports all PyTorch vision library models and well-known datasets like CIFAR-10, CIFAR-100, MNIST, FashionMNIST, and SVHN. Users can start without additional setup, but the toolkit also allows for custom datasets and models, offering flexibility for various research and applications.

Architecture

The high-level architecture of the toolkit is shown in the figure below.

The toolkit is designed to be modular and extensible. CLI and Python API are implemented separately, however, they share the same core components and they have the same package structure for the sake of consistency. Tests are implemented for both CLI and Python API to ensure the correctness of the implementation and again they follow the same structure. The toolkit is designed to be easily extensible, new attacks, defenses, and evaluation metrics can be added by implementing the corresponding classes and registering them in the corresponding registries.

Testing

The library is tested using pytest and coverage is measured using coverage. You can run the tests using the following command:

pytest tests/

Some tests take longer to run. To speed up the tests, you can use the --device option to run tests on a specific device (e.g., --device cuda:0).

pytest tests/ --device cuda:0

Tests are categorized into the following groups:

• cli: tests for the command line interface
• advsecurenet: tests for the Python API
• essential: tests for essential functionality (e.g., smoke and unit tests)
• comprehensive: tests for comprehensive functionality (e.g., integration tests)
• extended: tests for extended functionality (e.g., performance tests, security tests)

You can run tests for a specific group using the m option and the group name. For example, to run tests for the CLI:

pytest tests/ -m cli
